+# Peer-to-Peer Messaging Application GSoC 2024
+
+## Chosen Goals
+1. Implement on-device user authentication for enhanced security.
+2. Complete integration of RSA encryption to secure messaging.
+3. Enable seamless sending and viewing of files, images, audio, and video.
+4. Enhance the user interface to support intuitive file viewing.
+5. Update project dependencies for improved performance and stability.
+
+## Project Overview
+The Peer-to-Peer messaging application aims to create a decentralized messaging platform, eliminating reliance on 
+centralized servers vulnerable to privacy breaches. By leveraging device networking capabilities, the app ensures 
+robust communication even in disaster-prone or remote areas with weak cellular connectivity.
+
+## Detailed Progress and Achievements
+
+### Security Enhancements
+- **User Authentication:**
+    - Implemented password and fingerprint locks for on-device user authentication using the `local_auth` package.
+    - Ensured secure access to the app, enhancing user privacy and data protection.
+
+- **RSA Encryption:**
+    - Integrated RSA encryption for secure messaging between connected clients.
+    - Utilized libraries like `rsa_encrypt`, `asn1lib`, `dart:typed_data`, `dart:convert`, and `pointycastle` for 
+      key generation, encryption, and parsing.
+    - Stored and transmitted public and private keys securely using `flutter_secure_storage` and `flutter_nearby_connections`.
+
+### File Handling
+- **File Sharing:**
+    - Implemented secure file sharing functionality for sending files, images, audio, and video between users.
+    - Ensured encryption of transmitted files to prevent unauthorized access.
+    - Used `file_picker`, `open_file_x`, `permission_handler`, and `path_provider` for file operations.
+
+- **File Viewing:**
+    - Developed a user-friendly UI for in-app file previews and viewing.
+    - Supported all file types for seamless user experience within the chat interface.
+
+### UI Enhancements
+- **Chat Interface:**
+    - Enhanced the chat UI by adding date indicators and chat bubbles for a more intuitive messaging experience.
+    - Created a clean and organized UI specifically for viewing shared files within the chat.
+
+### Dependencies and Testing
+- **Dependency Management:**
+    - Updated all project dependencies and packages to their latest versions.
+    - Ensured compatibility and stability across multiple devices and platforms through rigorous testing.
+
+## Next Steps
+- **Finalize RSA Encryption for Files:**
+    - Complete the implementation of RSA encryption specifically for file sharing to bolster security.
+
+- **UI Refinements:**
+    - Continue refining the user interface based on user feedback to improve usability and aesthetics.
+
+- **Testing and Validation:**
+    - Conduct comprehensive testing to validate the app's security, performance, and user experience.
+
+- **Prepare for App Publication:**
+    - Prepare the app for publication on the Google Play Store and Apple App Store.
+    - Ensure compliance with all guidelines and requirements for app submission.
+
+## Conclusion
+The progress achieved during GSoC 2024 has significantly enhanced the security, functionality, and user experience 
+of the Peer-to-Peer messaging application. By implementing robust authentication mechanisms, advanced encryption techniques,
+and seamless file sharing capabilities, the app is well-positioned to offer users a secure and reliable communication platform. 
+Moving forward, the focus will be on finalizing remaining features, refining the UI, conducting thorough testing, and 
+preparing for app publication to reach a broader audience.
